I don’t write much about kokanee and sockeye, but they are part of the effort to reintroduce anadromous fish into the upper Deschutes Basin. The tribes frequently talk about the cultural significance of sockeye but they seem to be of secondary importance in reintroduction efforts. As a fly angler who likes to target large fish, I am also very aware that kokanee are the primary food source for bull trout in Lake Billy Chinook.Read More »
The annual Pelton Round Butte Fisheries Workshop is rapidly approaching so I have been reviewing notes from last year along with updates since then. I’ll make a few posts from that review over the next week. Like I have said before, if you are interested in learning about what is really happening in the lower Deschutes River, Lake Billy Chinook, and anadromous fish reintroduction efforts, you should attend.
Portland General Electric has recently been talking about above average returns of reintroduced spring chinook this year. I first saw mention of this in their June newsletter, then there was this story on KTVZ, and then today’s story in the Bend Bulletin. I hesitated to write about these returns but given the coverage, here’s my two cents. Without a doubt this is good news but with a total of 46 adult fish so far this year returns remain dismal. PGE is crediting the improvement to operational changes, specifically releasing hatchery reared smolts rather than fry along with nighttime operation of the Selective Water Withdrawal tower during out migration periods. I certainly hope these are the reasons. Time will tell, however, if this is an aberration, like the recent one year spike in Sockeye returns that has not repeated itself, or the beginning of a true recovery. I’m hopeful, but cautious.
As I have written about repeatedly in the past, if you want to hear the latest science and updates on what is happening in the Lower Deschutes, you should attend the Pelton Round Butte Fisheries Workshop. The 25th annual workshop is next month, July 17 & 18, at The Riverhouse Convention Center in Bend. You can sign up and get the agenda here. This meeting should be especially interesting. Along with the normal updates on salmon and steelhead reintroduction efforts, the results of the long overdue water quality study will be released. You can read the latest PGE/CTWS newsletter via the link above. The complete water quality study will be posted on their site on June 20, so come to the workshop prepared to ask questions. I hope to see you there and, as usual, will post my summary of the meeting.
Yesterday ODFW released their projections for 2019 summer salmon and steelhead returns for the Columbia River basin. The outlook is for another bleak year. “Due to the low projected returns for upriver summer steelhead, additional protective regulations are needed this fall including a one steelhead daily bag limit and area-specific steelhead retention closures. The rolling 1-2 month closures start in August and progress upriver following the steelhead return to reduce take of both hatchery and wild fish. These closures affect the mainstem Columbia and the lower reaches of specific tributaries.” This includes the Deschutes below Moody where only one hatchery steelhead may be kept all year (June 16 – December 31) but none from August 1 to September 31.
The official Deschutes steelhead season is from April 1 to March 31, so the 2018/2019 season is now over. Today, PGE released their March monthly newsletter which stated that a total of 35 upper basin origin adult steelhead returned and were passed above the Pelton Round Butte project and released into Lake Billy Chinook. Clearly, this is a dismal number. You can see the number of smolts that were released downstream here. Assuming that adult returns were from 2016 smolts that’s a return rate of only 0.87% (not 8.7%, I missed a decimal point in the original post). There is hope for some improvement in the adult return count, however, if not the percentage. In 2017 and 2018 steelhead smolt counts were much higher. 2017 was a better water year and in both years more smolts were planted. Starting next year only smolts will be planted. Read more about this here.
This spring marks the last stocking of fry as part of the upper Deschutes Basin salmon and steelhead reintroduction effort. Yesterday I was part of the crew helping with the final chinook salmon fry stocking and backpacked fry into the lower Crooked River canyon as well as where Alder Springs meets Whychus Creek not far from the middle Deschutes. As I wrote about here, the reintroduction effort has been a disappointment for many reasons one of which is the unsuccessful fry stocking effort and a new approach is needed.Read More »
